AUTOGRAPHIC MANIFOLDING AND REGISTERING MACHINE.

SPECIFICATION forming part of Letters Patent N 0. 462,665, datedNovember 3, 1891.

Application filed May 20, 1890. Serial No. 352,438. (No model.)

To CLZZ whom, it may concern:

Be it known that we, JOHN XV. DICK and ARTHUR L. EASTIN, citizens of theUnited States, residing in the city of St. Louis and State of Missouri,have invented certain new and useful Improvements in AutographicManifolding and Registering Machines, of which the following is a full,clear, and exact description.

Our invention relates to improvements in that class of machines known asautographic registers, used for making several copies of a memorandumsimultaneously with,

the production of the original, and in which there is generally providedmeans for preserving one or more of the copies for future reference, soas to be inaccessible to the person using the machine.

Our invention consists in the combination, with the supply-roller, of alarge frictionwheel mounted on the shaft thereof, a copysheet-receivingspool loosely j ournaledin the frame and having a friction-wheel securedto its shaft, an interposed sWingingfriction-roll, a spring for holdingsaid frictional rolls in frictional contact, and a paper-supportingplatform intermediate the supply and copyreceiving rolls.

In the accompanying drawings, in which like letters of reference denotelike parts in the several figures, Figure 1 is a side elevation of ourimproved machine with the rear side of the containing-case removed. Fig.2 is a plan view of the same with a portion of the supporting-platformfor the writing-surface removed and portions of the memorandum andcarbon sheets torn away, showing the superposed position of the severalsheets. Fig. 3 is an end view of our machine with a portion of thecontaining-case removed, showing the copy-receiving mandrel and the pinsthereon for securing the end of the sheet wound 011 it, also showing theslot in the end of the containing-case. Fig. 4 is a side view of thecopy-receiving spool, showing the removable end. Fig. 5 is an end viewof the copy-receiving spool, the detachable end removed, showing theinclination of the pins for securing the end of the sheet of paper.

In our machine we inclose the working parts in a containing-case A, madein two parts a and a, the upper part or lid to being secured at one endto the lower or box part a by a hinge and fastened at the other end witha lock. The top of the lid to is made, preferably, of sheet metal, withthe middle portion thereof cut away, forming a frame or scroll B, forholding the paper flat and exposing, a portion of the top sheet on whichto write the memorandum. One end of the frame 13 is extended beyond themargin of the box and beveled, forming the eutting-edge b, against whichthe paper can be torn in separating the memorandum slips from the'sheetsin the machine. Immediately under the cuttingedge the material of thecoi'itaining-case A is cut away, forming the slot b across the upperedge of that end of the containing-case through which the sheets ofpaper are passed to the outside of the containing-ease. The framework 0for supporting the working parts of the machine is made to fit snuglythe containing-case A when the lid a is closed down. The platform D forsupporting the sheets of paper when being written on is supported by theframe C immediately under the opening in the frame B. The platform D isformed with a raised edge (Z along each side, leaving a shallowlongitudinal groove throughout the length of the supporting-platform D alittle wider than the width of the sheets of paper used, acting as aguide for the sheets and preventing the frame B from binding onthepaper. The depth of this groove formed by the raised edges d isgoverned by the number of sheets of paper used on the machine. In thedrawings it is somewhat exaggerated in order to properly show the sheetsof paper.

The journal-bearings in the frame 0 for the ends of the supply-rollmandrel Eare formed in the ends of inclined slots 2, so that thesupply-roll can be convenientlyinserted in or removed from the machine.On one end of the mandrel E there is rigidly secured the largefiat-faced friction-wheel F. The mandrel G for the preserved copy rollor spool, which has its journal-bearings in the frame 0, carries on oneof its ends a small friction wheel or pulley c. The journal-bearing forthe shaft or mandrel G at this end is a slot 7i, cut in the frame 0, soas to permit of an adjustable movement of the end of the mandrel G,carrying the friction-pulley c in a direction toward and from thefriction-wheel F. It has been found preferable to place an intermedlatefriction-wheel H between the two wheels or pulleys F and c. on the freeend of an arm 1?, which is pivotally secured at its other end to theframework O, so as to freely assume a position between the two wheels Fand c and merely transmit the motion of rotation from one-to the other.The proper friction between the faces of the wheels is produced by thespring k the tendency of which is to press the friction-wheel 0 againstthe wheel H, and this beingfree to move against the large wheel F. Theoffice of this combination of frictionwheels is to operate the copy-rollmandrel in roll mg up the preserved copy-sheet by the rotation of themandrel of the supply-roll caused by the unwinding of the paper on it.

It'is obvious that the mandrel G for the copy-roll will have to travelfaster relatively when the paper is first started on it and the roll ofpaper on the supply-mandrel E is larger than when the paper on thesupplymandrel has been partly used and unreeled and the roll on themandrel G larger. The proportionate size of the two wheels F and c issuch and the friction between them sufficient to keep the copy-sheetrolled up and taut at first, and when the conditions become.

such that it is not necessary for the copy-roll to rotate so fastrelatively its friction-wheel will slip on the other. The sheets ofpaper are carried from the supply-roll on the mandrel E over independentrollers 0 0' 0", which have their journal-bearing near the upper edge ofthe frame 0 so separated as to leave room for the recesses 97. n, cut inthe upper edge of-the frame 0 to accommodate the ends of theclamping-rods m m, which are used to secure the ends of the sheets ofcarbonpaper. This arrangement permits of the carbon-sheets t if beingproperly interleaved between the memorandum-sheets mt 'u." and securelyheld there. The lower memorandum-sheet is carried down over the roller 8at the other end of the writing-table D and the end secured to themandrel or spool G. The end of the paper is secured to the spool bypressing it over two short pins 41;, protruding from the surface of thematerial of.the spool G near each end, which are slightly inclined inthe direction of rotation of the spool This wheel H is mounted inwinding up the sheet of paper, so that when the roll of paper is turnedas a whole on the spool in the opposite direction from which it waswound the roll will be loosened and will slip off the retaining-pins 0c.The roll can then be slipped off the spool, one end of which isremovable for that purpose.

The comparative wide part K of the frame B at one end of the top of thebox forms a convenient resting-place for the hand when writing on themachine.

When the memorandum has been written on the machine, the protruding endsof the paper are grasped and pulled out and torn off. In polling thesheets the supply-roll on the mandrel E is rotated, and with it, bymeans of the friction-wheels mounted on the same, the mandrel G, whichtakes and reels up the copy-sheet, the end of which has been fastened toit.

It may in practice prove preferable to secure the carbon-papers in theirposition between the memorandum-sheetslby clamping devices secured tothe sides of the platform D and pass the several sheets ofmemorandum-paperover the same roller, thereby doing away with thefriction of the other rollers.

If it is not desired to preserve a copy, as is done in the machinedescribed, the copy-roll can be dispensed with and all the sheetswithdrawn together.

We claim In a manifold-copying machine, the combination, with thesupply-roller, of a large friction-wheel mounted on the shaft thereof, acopy-sheet-receiving spool loosely journaled .in the frame and having afriction-Wheel secured to its shaft, an interposed swinging 9ofriction-roll, a spring for holding said friction-wheels in frictionalcontact, and a papersupporting platform intermediate the supply andcopy-receiving rolls, substantially as and for the purposes described.

In testimony whereof wehave affixed our signatures, in presence of twowitnesses, this 9th day of May, 1890.
